Flower color in snapdragons results from the amount of the pigment anthocyanin in the petals. red flowers are produced by plants that have full anthocyanin production, and ivory-colored flowers are produced by plants that lack the ability to produce anthocyanin. the allele an1 has full activity in anthocyanin production, and the allele an2 is a null allele. dr. ara b. dopsis, a famous genetic researcher, crosses pure-breeding red snapdragons to pure-breeding ivory snapdragons and produces f1 progeny plants that have pink flowers. he proposes that this outcome is the result of incomplete dominance, and he crosses the f1 to test his hypothesis. what phenotypes does dr. dopsis predict will be found in the f2 and why?

1 offspring will be red in color

1 offspring will be ivory in color

2 offspring will be pink in color

Explanation:

Given -

Allele An1 shows full activity in anthocyanin production and thus are red in color

Allele An2 shows null activity in anthocyanin production and thus are ivory in color

Genotype of pure-breeding red snapdragons is An1An1

Genotype of pure-breeding ivory snapdragons is An2An2

F1 generation -

An1An1 x An2An2

An1An2, An1An2, An1An2, An1An2

F2 Generation -

An1An2 x An1An2

An1An1, An1An2, An1An2, An2An2

The output will be

1 offspring will be red in color

1 offspring will be ivory in color

2 offspring will be pink in color

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
